What Ai Wen cares about the most is the strange lines on the locket.

He always had a sense that there was some secret hidden in it, even though both Dumbledore and Voldemort had come into contact with the locket and found nothing.

But I don't know why, but Evan just feels that way.

Dumbledore glanced at Aven and immediately returned to normal, with an extremely calm expression on his face, as if nothing had happened.

He waved his wand and dragged the boat with his magic. Now, no one but him knows how much magic Aven has now.

Sirius, Harry, and Hermione were also a little surprised, but they didn't think much of it.

In their opinion, it is already a miracle that such a small boat can carry so many people. After Aven came up, the reason why the boat sank quickly may be because it has reached a critical limit.

Dragged by Dumbledore, the boat set off at once, and there was silence except for the soft rustle of the bow piercing through the water.

The boat was moving autonomously, and without their hands, there seemed to be an invisible rope pulling it towards the green light in the middle of the lake. Soon, the rock walls of the cave were out of sight, and they felt as if they were on the sea, only there were no waves around.

As the boat moved, the wand's light shimmered on the black water.

The boat cut deep ripples into the glass-smooth surface of the lake, like grooves in a black mirror

Just then, Harry suddenly screamed in horror, "I see, those Yin Corpses are not far below the water. ”

Evan looked over where Harry had pointed, and in the light of his wand he saw a dead man lying on his back a few inches above the water: his eyes were foggy and like cobwebs in them, and his hair and robes swirled around his body like smoke.

It was obviously a dead corpse, but his eyes were covered with cobwebs, but he followed them extremely strangely, and the eyes inside were quietly turning.

The corpse seemed to be ready to jump out and attack them at any moment, but it didn't move until the boat rowed by.

"They didn't find out who we were, but I'm sure they'll be less quiet when we touch Voldemort's mechanisms!" Dumbledore whispered, "It's almost there, Voldemort's purpose has been accomplished, and a lot of my magic has been consumed to keep the boat from sinking." ”

Evan turned his head to look at Dumbledore, and listened to what he meant, the white light mist he used to drag the boat was very mana-consuming, or he was already using his own mana, which was up to the standard required by the boat.

He was suddenly a little worried, what would they do if Dumbledore had no more magic.

Aside from Dumbledore, there was no one here who was the match for the thousands of Yin Corpses.

After a few minutes, the green light in the center of the lake seemed to finally get bigger and brighter. The boat gently slammed into something and stopped.

Evan didn't see it at first, but when Harry raised his glowing wand, he saw them on a smooth rocky island in the middle of the lake.

"We're here, be careful not to touch the lake. Dumbledore warned again.

Everyone climbed down from the boat in turn, and Evan was the first, jumping off the boat to get back to his original state, and quickly pulled out his wand.

Behind him was Hermione, who looked finally relieved.

Then Harry, Sirius, and finally Dumbledore, used his wand to retract the mist of light that floated beneath the boat.

Evan looked at the island in front of him, about the size of Dumbledore's office: a flat, black slab of stone that was empty except for the green light source. Now that I look closer, the green light is much brighter.

Evan squinted at it, and he saw that the green light was coming from an ancient round stone basin with a pedestal underneath it.

Dumbledore approached the stone basin, and the others hurried over.

They are centered on a stone basin and stand side by side around it. Inside the stone basin was a basin full of emerald green liquid, emitting a shimmering phosphorescence.

Following the method that Dumbledore had just given him, Evan struggled to feel the traces of magic left on the liquid.

The magic was very strong, but it wasn't the magic he was familiar with, and he couldn't tell what it felt, it was very strange.

In addition to these liquids, the stone basin and base used to hold the liquid do not seem to be ordinary, and they have strong defensive magic on them.

Evan looked closely, and the more he looked, the more frightened he became.

There was a powerful magic hidden in the green liquid in front of him, and it was very evenly distributed, he didn't know what kind of potion it was, and what kind of magic was applied on the stone altar, and in all the knowledge he knew, none of it could be used.

If it weren't for the fact that he already knew the result and let him use his own strength to solve it, to tell the truth, Ai Wen didn't know what to do at all.

As for Sirius, Harry, and Hermione standing on the sidelines, with a confused face, it is even more impossible to know.

It can be seen that Voldemort's strength and magic theory level surpass them and ordinary wizards by a lot.

"Professor, what is this?" Harry couldn't help but ask.

"I can't be sure!" Dumbledore whispered, taking a closer look at the stone basin and the liquid inside, "the only thing that is certain is that this is something more worrying than blood and corpses, and I'm glad we've taken out what was hidden inside." ”

Dumbledore observed for a moment, then shook the sleeves of his robe upwards, the tips of his fingers reaching for the surface of the liquid.

"No, don't touch it!" shouted everyone in unison.

"It's not that simple, I can't touch it. Dumbledore smiled faintly, "See, I can't stretch my hand any further, you can try it." ”

Sirius, Aven, Harry, and Hermione hesitated, and their fingers reached deep into the stone basin to touch the liquid.

However, they encountered an invisible resistance, and their hands could not approach the liquid.

No matter how hard you push down, the tips of your fingers seem to touch the hard, indestructible air, and the liquid itself does not change at all.

"Please give me a try, I think this spell might work!" Dumbledore said, raising his wand and making some complex movements on the surface of the liquid, muttering something silently.

However, there was no movement.

The phosphorescent glow of the green liquid seemed to be brighter, and Evan and the others watched in silence as Dumbledore did so until he withdrew his wand.

"Professor?"

"Remarkable, remarkable!" Dumbledore said appreciatively, "If I'm not mistaken, this is probably Voldemort's own invention of the potion, and I have to say that he is indeed the best of all the graduates of Hogwarts has ever been." ”

"But you'll be able to crack it, won't you?" said Harry hopefully.

"No, I can't, Harry!" Dumbledore shook his head, "this liquid, you can't put your hand in, you can't separate it, scoop it dry, or drain it, you can't make it disappear with an vanishing charm, you can't deform it with magic, or you can't change its properties in some other way. I can only conclude that this liquid needs to be drunk!"

"Drink it?!" everyone else looked at him in surprise except for Evan.

"Yes, at least I think so, only by drinking it can the stone basin be emptied and the contents obtained. Dumbledore said calmly, "From this point of view, I have to admire Regulus, his sacrifice is very meaningful. (To be continued.) )
